I'm in the process of building my first reef tank and I'm thinking that I will want to buy an RODI filter system for generating my tank water. I had some questions about how they work. I've been looking at the 100gpd ones that "purewater club" is selling on ebay. So how exactly do the logistics of these filters work? Do you need to have a holding tank on both ends of the system as storage? Or do you attach one end to the tap and place the output in a bucket. Is it something you can set up and let run all day (in order to make the 100gpd) or do you need to supervise the process.

How do most of you set up and run your systems? Is an RODI filter an absolute must? I'm on the city of Seattle's water system which has high quality water, but I don't know about things like silicates or phosphates etc. Alternatively, I live across the street from Puget Sound so I have a source of readily accessible sea water, even though its salinity is a bit low and would need to be brought up (28 ppt, don't know what that equals in SG). Anyone here use natural sea water?

Thanks!
